This is something I ran into with my own project (I need txpool_content to be precise). Is there any particular issue holding this up, or it is just blocked on missing time? Is this something that will come any time soon, or are many other things higher priority?

No one else has asked for it, as far as I know. So it hasn't been prioritized.

There are other issues ahead of this, like getting Ganache v7 to a stable release. After that we can evaluate adding these methods.

Please feel free to work this issue if you don't want to wait for us. Here is where our tx pool transactions are held:

You just need to add the RPC methods you need to api.ts and that would make it available over RPC.

You'd build the tx pool content by accessing the transaction pool like this:

const { transactions, common } = this.#blockchain;
const { transactionPool } = transactions;

transactionPool.origins // contains queued txs (see https://github.com/trufflesuite/ganache/blob/434d971f7305c66dabe7b65173d6f5583d930025/src/chains/ethereum/ethereum/src/transaction-pool.ts#L400-L409 for how to loop over this object!)
transactionPool.executables // contains pending txs

You can get the json RPC representation of each transaction by calling transaction.toJSON(common).

Thanks for the pointers, they seem very helpful!

Adding below methods would be straight forward now that we have txpool_content present.
txpool_contentFrom
txpool_inspect
txpool_status

Should I start working on this (if anyone isn't)? Also, if yes, single PR for all or one for each?

Also, #1539 (comment)

@amandesai01 Go for it! Regarding that comment about the processMap function. Maybe you could move it to a new helper function exported from transaction-pool.ts. Maybe name it something like mapToJSON (I'm bad at naming things... other ideas welcome!)

It's your call, whatever you prefer!
